Background technology
Be used for making the fuel of internal combustion engine operation such as gasoline or the contained sulphur of diesel oil at it oxidation to occur when internal combustion engine burns, thus generation oxysulfide such as sulfuric acid.Part oxysulfide enters the lubricating oil for lubricating engine, and remainder is discharged with other waste gas.The oxysulfide of discharging with other waste gas causes environmental pollution.Therefore, up to now, the sulphur content in the fuel is subject to strict supervision.Control for sulphur content is applicable to gasoline (fuel that is used for petrol motor) at first.Yet, also be applicable to recently to have the more diesel oil fuel of high sulfur content for the control of sulphur content.Sulphur content in the diesel oil fuel is defined as recently and is not higher than 0.0010 % by weight.
Because sulphur content reduces, lubricating oil than low degree be subject to the oxysulfide that produces when the fuel combustion such as the pollution of sulfuric acid.This means the consumption that can reduce metallic high alkaline detergent in the lubricating oil.Metallic alkaline purification agent is used for the oxysulfide of neutral lubrication oil.
When fuel burns, be not only fuel, and parts of lubricating oil is burnt in engine also in engine.Also discharged with other waste gas by the gas that the lubricating oil that burns produces.Therefore, needs reduce the sulphur content in the lubricating oil.
In addition, the most recently used lubricating oil for IC engines comprises base oil (hydrocarbon ils with lubricant viscosity) and various additive (being lubricating oil additive), the metallic alkaline purification agent of the oxysulfide that produces as being used for neutralizing, for keeping base oil to move at elevated temperatures and avoiding deteriorated oxidation retarder, the dispersion agent of the resistates that be used for to disperse the cigarette ash that produced by fuel combustion and produced by the deteriorated of the containing metal purification agent of base oil and base oil, be used for preventing piston and the stuck extreme pressure agent of cylinder, for reducing betiding the low friction compound (friction modifier) that rubs between piston and the cylinder.
Therefore, when lubricating oil composition burnt, the phosphorus component and the metal component that place the additive of lubricating oil composition to comprise decomposed, and enter in the waste gas with the form of phosphorous oxides and metal oxide.The phosphorous oxides that comprises in the waste gas contacts with the oxide catalyst that places waste gas purification apparatus or reducing catalyst with metal oxide, and makes catalyst deactivation.
For the above reasons, need to reduce sulfate ash content, phosphorus content and the sulphur content of lubricating oil composition.
Patent disclosure text 1 (JP2002-53888A) discloses a kind of lubricating oil composition that is advantageously used in the oil engine, particularly diesel engine that lubricate the fuel that uses low sulfur content.It is 0.1 % by weight or still less base oil and the following additive of (preferred 0.03 % by weight or still less) that disclosed lubricating oil composition comprises sulphur content:

Following cl content and the consumption of sulfate ash content, the phosphorus content of 0.01-0.1,0.01-0.3 % by weight sulphur content, 40 ppm by weight that this lubricating oil composition has the 0.1-1 % by weight is 0.2-7 % by weight (preferred 0.5-5 % by weight, more preferably 1.0-3 % by weight) the organic acid salt that derives from metallic purification agent
Wherein above-mentioned content and consumption represent based on the total amount of lubricating oil composition.
Patent disclosure text 1 also discloses disclosed lubricating oil composition in the example in work and has demonstrated good high temperature detergency in oil engine.
Patent disclosure text 1 also discloses lubricating oil composition can contain molybdate compound, and it can be used as friction modifier, oxidation retarder and anti-wear agent.Described molybdate compound can be one of known molybdate compound, such as sulphur molybdenum oxide dithiocar-bamate, sulphur molybdenum oxide dithiophosphates and the molybdenum complex that may contain the succinimide of sulphur.
Patent disclosure text 2 (JP 2004-149802A) discloses the lubricating oil composition of a kind of low sulfation ash oontent, low phosphorus content and low sulfur content, it is preferably used for lubricated oil engine (being machine oil), and it comprises base oil, the ashless dispersant of the inferior second fat of carbonic acid aftertreatment, ashless dispersant, overbased metal-containing detergents and the phosphorus compound of boration.Patent disclosure text 2 also discloses disclosed lubricating oil composition can comprise molybdenum-succinimide complex compound.In the work example of patent disclosure text 2, data show that described lubricating oil composition shows good oxidative stability and good resistance to abrasion by experiment.

The oil that mineral oil preferably can obtain in the following way: the lubricating oil distillate of mineral oil is processed by solvent refined, hydrogenation or its combination.Particularly preferably be highly hydrogenated refining oil and (corresponding to hydrocracking oil, usually have 100 to 150 viscosity index, 5 % by weight or aromatic component still less, 50 ppm by weight or nitrogen content still less, and 50 ppm by weight or sulphur content still less.Particularly preferably be the high viscosity index (HVI) base oil, for example the viscosity index that obtains of the hydroisomerization by soft wax or GTL wax (gaseous state is to liquid) is the base oil of 140-160.
The example of synthetic oil (synthetic lubricating base oil) comprises polyalphaolefin, as has the polymerizable compound of the alhpa olefin of 3 to 12 carbon atoms; Diprotic acid such as sebacic acid, nonane diacid or lipid acid and have the dialkyl of the alcohol of 4 to 18 carbon atoms are generally the dioctyl sebacate; Polyol ester, it is 1,1,1-TriMethylolPropane(TMP) or tetramethylolmethane and the monacid ester with 3 to 18 carbon atoms; Alkylbenzene with the alkyl with 9 to 40 carbon atoms.Synthetic oil is basic sulfur-bearing not usually, demonstrates for the good stability of oxidation and good thermotolerance, and produce less residual carbon and cigarette ash when burning.Therefore, preferably synthetic oil is used for lubricating oil composition of the present invention.Angle from purpose of the present invention particularly preferably is polyalphaolefin.
Can use individually each in mineral oil and the synthetic oil.Yet, if expectation can be used in combination two or more mineral oil, and can use in combination two or more synthetic oils.Can be used in combination mineral oil and synthetic oil with arbitrary proportion.
Ashless dispersant
Lubricating oil composition of the present invention comprises at least two kinds of different ashless dispersants, be thiazolinyl-or alkyl-succinimide or derivatives thereof (component a) and thiazolinyl-or alkyl-succinate or derivatives thereof (components b), the consumption 0.5-5.0 % by weight of respectively doing for oneself, preferred 1.0-4.0 % by weight, (described consumption is based on the total amount meter of lubricating oil composition).Preferably with 1:4-4:1, more preferably the weight ratio of 1:2-2:1 comprises component a) and components b).
